Hi Bill, at $560 it is a bit spendy for a chopper. Maybe Ralph will enlighten us if he know what is up with this engine. Not quite 5hp says the specs but it's getting close to enough power for projects I can think of, if it stays moderately light.

The appearance of more and larger 4 strokes probably means the manufacturers will continue perfecting and extracting more horsepower in the coming years. And yes $550 is pricey.
